What is a neural network?
- [Instructor] Image recognition is the ability for computers to look at a photograph and understand what's in the photograph. Here we're passing in a picture to the neural network, and the neural network is generating a label, dog, because that's the main object that appears in the picture. In the past few years, researchers have made huge breakthroughs in image recognition thanks to neural networks. Using neural networks, it's now possible to recognize objects and photographs with high accuracy. Let's take a quick look at the inner workings and structure of a neural network. A neural network is made up of separate nodes called neurons. These neurons are arranged into a series of groups called layers. Nodes in each layer are connected to the nodes in the following layer. Data flows from the input to the output along these connections. Each individual node is trained to perform a simple mathematical calculation and then feed its result to all the nodes it's connected to. The neural…
